====== FTP Server ======

The built-in FTP (File Transfer Protocol) Server is an alternative way to transfer files to/from your router and its attached storage. This menu contains settings to configure that server. It is divided into sections including: FTP Server Configuration, Directories, Limits, Custom Configuration and User Accounts.

Before using FTP, you may want to consider the pros and cons of using it versus the NFS Server (in a *nix environment) or File Sharing via Samba. There are significant differences between them.


===== FTP Server Configuration =====

  * and more.\\  \\


===== Directories =====

**Anonymous Root Directory:**  This specifies the filesystem location visible to anonymous connections.

**Public Root Directory:** This specifies the filesystem location accessible to any defined FTP user.

**Private Root Directory:** This filesystem location is accessible only by the owner. Each user will have a protected subfolder under this location.

**Directory Listings:  **This setting controls users' ability to do directory listings.

  * Enabled - Users are permitted to do directory listings.
  * Disabled - Users are not permitted to perform listings.
  * Disabled for Anonymous - Anonymous users aren't permitted to do directory listings.


===== Limits =====

**Maximum Users Allowed to Log in:**  This sets the maximum number of logged-in users at once. Users above the limit are rejected.

**Maximum Connections from the same IP: ** FTP lets a user log on via multiple sessions from the same address. Here, specify how many simultaneous connections will be allowed for the same user.

**Maximum Bandwidth for Anonymous Users:**  FTP throttling will limit the amount of bandwidth available to what's specified here for each anonymous user.

**Maximum Bandwidth for Authenticated Users:**  FTP throttling will limit each authenticated users' bandwidth to this amount.

**Idle Timeout:**  This specifies the timeout period, in seconds, until a user is disconnected due to inactivity.

**Limit Connection Attempts:**  This option works when FTP is enabled on the WAN. If selected, new fields appear where you can define the maximum number of logon attempts in a given time period. Further connection attempts will be rejected.\\


===== Custom Configuration =====

This is the area where you define FTP user accounts. User accounts defined here will be given only FTP service rights. No operating system accounts are created.

**Username:**  Here, enter the ftp user account name.

**Password:**  Here, enter the ftp user account password.

**Access:**

  * Read/Write - The FTP user is given read and write access.

 \\

**Read/Write:**  Choosing this setting provides the user full access.

**Read only**:  Choosing this settings allows the user only to browse and download.

**View Only:**  Selecting this setting mean the user can only browse directories.

**Private:**  Choosing this will mean the user can only access their own folder (and not the public area).\\
